As regards to fetuin-A and NAFLD, the following clinical characteristics had a positive effect on the SMD: BMI (β BMI = 0.0636, SE = 0.0437, p = 0.158), age (β age = 0.0057, SE = 0.0090, p = 0.529), AST (β AST = 0.0052, SE = 0.0077, p = 0.502), ALT (β ALT = 0.0018, SE = 0.0054, p = 0.734), GGT (β GGT = 0.0031, SE = 0.0074, p = 0.674), and TG (β TG = 0.0321, SE = 0.6628, p = 0.962). The gene discussed is TG; the disease is metabolic dysfunction-associated steatotic liver disease.
